I think most others already steered you in a good direction as for as hardware goes.
But I did see a under estimated liquid cooling bill,
I would plan spending ~$1500+ for everything, when it comes to liquid cooling it gets $$ pretty quick.
My Suggestion (for WC):
CPU Block: ~100 Raystorm
MB Block: ~150 Depends of course on the MB you buy, but imo go with EK
GPU Block 300 (for 2 blocks) I'm an EK fanboy for GPU Blocks, but I like Heatkiller as well
RAM Block (optional): 50 EK
Radiators: ~300 (assuming at least 2 360's) Alphacool, 80mm Thick Rad, I'm thinking of buying 2 of them.
Pump: 100 - 200 (1 or 2 Pumps?) MCP35X or MCP655 Also getting the Pump Tops (which cost extra)
Reservoirs: ~ 50 - 150 (1 or 2?)
Tubing Rigid / Soft ~10 - 30
Lots of Fittings! ~ 500 (imo depends on the case, how you route, and of course the tubing, but plan on gasping for breath at the sight of the bill!
Estimated Total: 1645
Of course you can get cheaper, but for what it sounds like you want to build, I think your going to be spending around 1500 or so for WC gear.
Some cheaper options are using the corsair H series (100 / 80) for cpu cooling. imo though if your spending 3k+ on hardware make it look / rock hard!
these are probably the top 3 (imo)
